Deep Measurement Electrode PairM 21-250
Ref.Nr. 31003250
Electrode pair espcially used for deep measurements
M 21-250
Have questions?Description
The deep electrodes M 21-250 were designed to measure the moisture content in structural moisture; in particular for deep measurements of all kinds of building materials.
By using the deep electrodes moisture profiles of the test object can easily be created. In order to ensure the conductivity between the material to be measured and the electrode pins, contact paste has to be used.
The electrodes should always be used in pairs and optimally placed at a distance of approx. 8 - 10 cm from each other in the material to be measured.
Measuring ranges
Structural Moisture
The electrode pair can be used with all hydromettes based on the resistance measurement method.
Resistance-based measuring
Measuring ranges
min.0 to max.87 digits
min.0.1 to max.60 wt.-%
min.0.1 to max.12 CM-%
The actual measuring range depends on the connected measuring instrument.
Show compatible measuring instrumentsSpecifications
- Measurements up until a depth of 10 cm are possible; the sample holes have to be prebored with a drill 8 mm Ø
- With the help of the electrodes a profile of the moisture content of the material to be measured can be compiled by measuring in layers
- The insulated stem prevents surface moisture from skewing the measuring result
